A numerical model of a dispersive, discrete-element nonlinear transmission line (NLTL) employing saturable inductors is reported and demonstrated to qualitatively reproduce the experimentally measured output of an NLTL. This numerical model is used with a genetic algorithm (GA) to optimize RF output power by varying the number of turns on each inductor at each stage and capacitance at each stage o...Show More
Modern power electronics systems try to maximize power density and efficiency. As such, the active switch is required to safely handle very stressful transient conditions. A 56 mm2, 180 A, SiC DMOSFET manufactured by Cree Inc. is evaluated by electrically stressing the device in a RLC ring-down test system capable of producing peak current in excess of 600 A (>3X rated current) and di/dt's as high...Show More
